Disklavier

I could be wrong, but since Roberto indicated he has a C3 Mark IV Pro, I
think he meant to write "*XP* extra-midi data", referring to Yamaha's
extensions to the MIDI stream providing high-res strike and release
velocity data for the Disklavier Pro.  The extra bits are sent using
certain MIDI NRPNs (non-registered parameter numbers).

(The confusion arose because Yamaha also has a spec called XG, an
extension to the General MIDI spec for the multitimbral use of MIDI.  
They've also defined an XF spec extending the lyric metadata events in
MIDI files.  Yamaha seems to like naming their specs X*.)

There does not seem to be any publicly-available sequencing software
that can conveniently edit Yamaha XP streams.  (By conveniently, I mean
software that automatically associates the NRPN extensions with their
corresponding notes and permits adding/deleting/editing such events as a
unit.  Trying to edit XP streams using conventional software like
Cakewalk requires the operator to manually associate the NRPN events
with the correct adjacent note events, and adjusting note velocities 
would be very tedious.

Yamaha and Zenph Studios surely have their own internal tools for this 
task but have not released them to others.
